The present disclosure relates to computer implemented methods and systems for data management, data analysis, and processing. The disclosed methods and systems can incorporate external data analysis into an otherwise closed data analysis environment. A typical environment for the systems and methods described herein is for assisting in a computer implemented method for building and updating a multi-dimensional cube data structure, such as, e.g., the systems and methods described in U.S. Pat. Nos. 7,058,621; 8,745,099; 8,244,741; and U.S. patent application Ser. No. 14/054,321, which are incorporated by reference in their entireties.

In an aspect, the methods and systems can manage associations among data sets with every data point in the analytic dataset being associated with every other data point in the dataset. Datasets can be larger than hundreds of tables with thousands of fields. A multi-dimensional dataset or array of data is referred to as an OnLine Analytic Processing (OLAP) cube. A cube can be considered a multi-dimensional generalization of a two- or three-dimensional spreadsheet. For example, it may be desired to summarize financial data by product, by time-period, and by city to compare actual and budget expenses. Product, time, city, and scenario (actual and budget) can be referred to as dimensions. A multi-dimensional dataset is normally called a hypercube if the number of dimensions is greater than 3. A hypercube can comprise tuples made of two (or more) dimensions and one or more expressions.

FIG. 1A illustrates an associative data indexing engine 100 with data flowing in from the left and operations starting from a script engine 104 and going clockwise (indicated by the clockwise arrow) to export features 118. Data from one or more data sources 102 can be extracted by a script engine 104. The data source 102 can comprise any type of known database, such as relational databases, post-relational databases, object-oriented databases, hierarchical databases, flat files, spread sheet, etc. The Internet may also be regarded as a database in the context of the present disclosure. A user interface can be used as an alternative or combined with a script engine 104. The script engine 104 can read record by record from the data source 102 and data can be stored or appended to symbol and data tables in an internal database 120. Read data can be referred to as a data set.

In an aspect, the user interface can be presented to a user to enable the user to generate a data set from one or more data sets stored in the data source 102 for the script engine 104 to extract and to be used as the basis for a data model. A data set can comprise one or more records. The one or more records can comprise one or more values for one or more fields. The one or more fields can comprise a numeric field (e.g., a number of sales, a number of products, etc. . . . ), a categorical field (e.g., a category such as a type of product, etc. . . . ), a date field, a time field, a geolocation field, a name field, etc. . . . .

The user interface can be configured to enable discovery of relationships between data sets and/or between records of a data set. The records of a data set can be represented on a canvas (e.g., display) by graphical objects. The graphical object can be any shape. By way of example, the graphical object can be a circle, a square, a triangle, and the like. Each graphical object can be labeled with a record name of a record underlying the graphical object.

In an aspect, the records of a data set can have one or more relationships amongst the records. As used herein, a relationship between two or more records can refer to a common attribute shared by the records, one or more common values shared by the records, combinations thereof, and the like. In some aspects, the records can have pre-established relationships, such as tables in a database that have a primary key-foreign key relationship. The pre-established relationships can be represented to a user on the canvas (e.g., display) by a proximity of one graphical object to another.

As shown in FIG. 1B, a plurality of graphical objects representing underling records can be displayed as particles 122. One or more fields 124 can be extracted from the records and displayed. The one or more fields 124 can be selected, causing the particles 122 to re-arrange. In the event none of the one or more fields 124 are selected, the particles can be displayed randomly, being attracted to the center of a viewing area. In FIG. 1B, the particles 122 are arranged based on a selection of the one or more fields 124 “host id”. The user interface can further display a repulsion slider 126 and an attraction slider 128. Adjustment of the repulsion slider 126 adjusts a degree of overlap of the particles 122. As the repulsion slider 126 is moved to the right, a repulsion force is increased, causing the particles 122 to push further apart from their neighbors. The attraction slider 128 also adjusts a degree of overlap of the particles 122, however, as the attraction slider 128 is moved to the right, an attraction force is increased, causing the particles 122 to move closer to their neighbors.

In another aspect, different sliders can be used. For example, a slider can be provided that permits adjustment of a distance between particles and adjustment of a distance between clusters of particles. The combined similarity score for each pair of particles i and j is being transformed into a target distance between visual representations of these particles on the 2-dimensional plane, the transformation formula takes particles distance and clusters distance as parameters:

TDij=ParticlesDistance+ClustersDistance*(1−CSij)

This means that the target distance between particles i and j will be larger if the combined similarity score is small, and will be smaller if the combined similarity score is large, and will be in the range [ParticlesDistance, ParticlesDistance+ClusterDistance].

Then a Metric Multi-Dimensional Scaling method can be applied for computing positions of the particles on the 2-dimensional plane trying to match the target distances between particles “as much as possible”, this algorithm is using gradient descent method for minimizing the stress function.

One or more of the one or more fields 124 can be selected for analyzing similarities of the records represented by the displayed particles 122. Selection of the one or more fields 124 causes a movement of the particles 122 on the canvas as a result of applying attraction forces and repulsion forces between them. The attraction force between two particles 122 is stronger if the similarity of values of the selected one or more fields 124 is higher. The movement of the particles 122 stops when all the particles 122 are located at positions where all forces (attraction and repulsion) applied to the particles 122 are in a balance, and all the particles 122 with similar values of the selected one or more fields 124 are located close to each other, and the particles 122 with dissimilar values of the one or more fields 124 are located further apart. As shown in FIG. 1C, one or more fields 124 have been selected. Specifically, “City,” “Property_Type,” and “Room_Type,” have been selected. The particles 122 are repositioned based on the similarities of the values of “City,” “Property_Type,” and “Room_Type.”

Any number of the one or more fields 124 can be selected to analyze similarity between records. The one or more fields 124 may be of different types (such as nominal, ordinal, or quantitive) and cardinality (one or many values per record). As shown in FIG. 1D, “City,” “bathrooms,” “bed_type,” “bedrooms,” “country,” “property_Type,” “review_scores_rating,” “room_type,” and “square_feet” have all been selected. The particles 122 are moved based on similarities between values of the selected fields for each of the records. The particles 122 are located based on their similarity—particles located closer to each other have higher similarity of “City,” “bathrooms,” “bed_type,” “bedrooms,” “country,” “property_Type,” “review_scores_rating,” “room_type,” and “square_feet.”

As shown in FIG. 1E, a selection 130 of a subset of the particles 122 can be made. The selection 130 of the subset of the particles 122 can be further analyzed. The selection 130 can be represented, for example, by a circle around one or more particles of interest. This allows analysis of records with properties similar to the record represented by a particle in a center of the selection 130. FIG. 1F illustrates a selection 134 of one or more fields 124 resulting in another rearrangement of the particles 122. The selection 134 can be made to select one or records underlying particles falling within the selection 134. FIG. 1G indicates the particles falling within the selection 134 by altering a color of the particles falling within the selection 134.

As shown in FIG. 1H, the records underlying the particles falling within the selection 134 can be analysed and one or more histograms 136 showing characteristics of the records underlying the particles falling within the selection 134 can be shown. Apart from analyzing distribution of attributes' values of the selection and comparing these distributions with distribution of the attributes' values for the whole dataset, the selected particles can also be assigned as a global selection, which allows visualization of the attributes of the selected particles in any visualization available via the methods and systems disclosed. Also, in an aspect, a selection description can be generated that captures characteristics specific to the selected particles in comparison to the overall dataset. The data set can be filtered, for example, based on the selection, which allows for focusing on the subset and analyzing the similarities of only selected particles. FIG. 1I illustrates an example interface. The example interface shows a selection description area 138 indicative of the underlying data. FIG. 1I also illustrates borders overlaid on to the canvas to provide a visual indication of the separation between groups of particles.

In addition to grouping and locating the particles 122 by similarities, a numerical attribute can be assigned to an x-axis and a y-axis of the canvas. Based on the assigned numerical attribute, the particles 122 can move towards a location based on a scale of the axis. As shown in FIG. 1J, “price_bucket” has been assigned to the x-axis. The particles 122 are then dispersed along the x-axis based on a value of the “price_bucket” field for the underlying records and keeping their relative locations based on the similarity for the other selected attributes. In an aspect, a color and/or a size can be assigned to the one or more fields 124, resulting in particles being colored or sized. In FIG. 1J, the particles 122 are colored by price_bucket.

In an aspect, an interactive discovery engine can be configured to determine similarities amongst records, determine resultant effects on positioning of particles based on the similarities, and arranging the particles accordingly. For example, the interactive discovery engine can utilize a Multi-Dimensional Scaling (MDS) technique that allows for computing positions of particles in a 2-dimensional or 3-dimensional space based on a measure of similarity (or dissimilarity) between each pair of records represented by the particles. In an aspect, a Metric Least Squares Scaling technique can be used that allows for computing an optimal position of particles by minimizing a predefined error function (also referred to as a stress function). Metric least squares scaling finds configuration points {x_(i)} in a p dimensional space with distances {d_(ij)} matching {δ_(ij)} as closely as possible, by minimizing a loss function S, e.g., S=Σ_(i<j)δ_(ij) ⁻¹(d_(ij)−δ_(ij))²/Σ_(i<j)δ_(ij).

In an aspect, the interactive discovery engine can determine a vector of similarities. The interactive discovery engine can compute the vector of similarities (which will contain a similarity score for each field in the data set of records) for each pair of values (v_(i), v_(j)) from a list of unique values of a record in a field (P). The interactive discovery engine can determine a similarity score for each field based on the type of field. For every application there could be domain specific attributes for which default rules of computing similarity scores could be slightly different. For example, for an attribute represents sales value, then the similarity can be computed by comparing a sum of these values instead of average values. A user can specify an expression that computes a similarity score for specific attributes. For example, field can be a numeric field, a categorical field, a date field, a time field, a geolocation field, combinations thereof, and the like. For numeric fields (nF), the interactive discovery engine can determine: 1−|average(nF, where P=v_(i))−average(nF, where P=v_(j))|/range(nF). For categorical fields (cF), the interactive discovery engine can determine: dotproduct(histogram(cF, where P=v_(i)), histogram(cF, where P=v_(j)).

The interactive discovery engine can then determine a combined score by calculating a dot product of vectors of similarities scores for selected fields. The interactive discovery engine can run iterations of a gradient descent method to optimize a stress function.

Similarity score of particles i and j for attribute k can be a numeric value sk[i,j] in a range [0, 1] that indicates how similar the particles i and j are based on their values of the attribute k: higher similarities are represented by higher score values and lower similarities by low score values.

Vector of similarities (S) of selected attributes can be computed for each pair of particles ([i, j], where i<j) and can be comprised of similarity scores for each attribute: Sij[k] is a similarity score for particles i and j based on the attribute k: sk[i, j].

The combined similarity score can be a single score value computed for each pair of particles ([i, j], where i<j) that indicates level of similarity of these particles based on all selected attributes, it can be computed by calculating length (aka magnitude) of the vector of similarities for the particles i and j using the Euclidean norm: CSij=|Sij|=Sqrt(Sum(Sij[k]{circumflex over ( )}2)).

Thus, the interactive discovery engine enables a user to quickly change the set of selected fields and see the changes in real-time of the relative positions of particles.

The records underlying a selection can be extracted for further analysis (e.g., used as a basis for a data model). For example, the records underlying a selection can be extracted and assembled into a data set. Returning to FIG. 1A, the records can be extracted from the data source 102. In an aspect, the extraction of the data can comprise extracting an initial data set or scope from the data source 102, e.g. by reading the initial data set into the primary memory (e.g., RAM) of the computer. The data extracted can comprise the one or more data sets selected by the user via the user interface 100 b. The initial data set can comprise the entire contents of the data source 102 base, or a subset thereof. The internal database 120 can comprise the extracted data and symbol tables. Symbol tables can be created for each field and, in one aspect, can only contain the distinct field values, each of which can be represented by their clear text meaning and a bit filled pointer. The data tables can contain said bit filled pointers.

In the case of a query of the data source 102, a scope can be defined by the tables included in a SELECT statement (or equivalent) and how these are joined. In an aspect, the SELECT statement can be SQL (Structured Query Language) based. For an Internet search, the scope can be an index of found web pages, for example, organized as one or more tables. A result of scope definition can be a data set.

Once the data has been extracted, a user interface can be generated to facilitate dynamic display of the data. By way of example, a particular view of a particular dataset or data subset generated for a user can be referred to as a state space or a session. The methods and systems can dynamically generate one or more visual representations of the data to present in the state space.

A user can make a selection in the data set, causing a logical inference engine 106 to evaluate a number of filters on the data set. In an aspect, a query on a database that holds data of placed orders, could be requesting results matching an order year of ‘1999’ and a client group be ‘Nisse.’ The selection may thus be uniquely defined by a list of included fields and, for each field, a list of selected values or, more generally, a condition. Based on the selection, the logical inference engine 106 can generate a data subset that represents a part of the scope. The data subset may thus contain a set of relevant data records from the scope, or a list of references (e.g. indices, pointers, or binary numbers) to these relevant data records. The logical inference engine 106 can process the selection and can determine what other selections are possible based on the current selections. In an aspect, flags can enable the logical inference engine 106 to work out the possible selections. By way of example, two flags can be used: the first flag can represent whether a value is selected or not, the second can represent whether or not a value selection is possible. For every click in an application, states and colors for all field values can be calculated. These can be referred to as state vectors, which can allow for state evaluation propagation between tables.

The logical inference engine 106 can utilize an associative model to connect data. In the associative model, all the fields in the data model have a logical association with every other field in the data model. An example, data model 501 is shown in FIG. 5B. The data model 501 illustrates connections between a plurality of tables which represent logical associations. Depending on the amount of data, the data model 501 can be too large to be loaded into memory. To address this issue, the logical inference engine 106 can generate one or more indexes for the data model. The one or more indexes can be loaded into memory in lieu of the data model 501. The one or more indexes can be used as the associative model. An index is used by database management programs to provide quick and efficient associative access to a table's records. An index is a data structure (for example, a B-tree, a hash table, and the like) that stores attributes (e.g., values) for a specific column in a table. A B-tree is a self-balancing tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic time. The B-tree is a generalization of a binary search tree in that a node can have more than two children. A hash table (also referred to as a hash index) can comprise a collection of buckets organized in an array. A hash function maps index keys to corresponding buckets in the hash index.

Queries that compare for equality to a string can retrieve values very fast using a hash index. For instance, referring to the tables of FIG. 2 , a query of SELECT*FROM Table 2 WHERE Client=‘Kalle’ could benefit from a hash index created on the Client column. In this example, the hash index would be configured such that the column value will be the key into the hash index and the actual value mapped to that key would just be a pointer to the row data in Table 2. Since a hash index is an associative array, a typical entry can comprise “Kalle=>0x29838”, where 0x29838 is a reference to the table row where Kalle is stored in memory. Thus, looking up a value of “Kalle” in a hash index can return a reference to the row in memory which is faster than scanning Table 2 to find all rows with a value of “Kalle” in the Client column. The pointer to the row data enables retrieval of other values in the row.

As shown in FIG. 5B, the logical inference engine 106 can be configured for generating one or more bidirectional table indexes (BTI) 502 a, 502 b, 502 c, 502 d, and/or 502 e and one or more bidirectional associative indexes (BAI) 503 a, 503 b, 503 c and/or 503 d based on a data model 501. The logical inference engine 106 can scan each table in the data model 501 and create the BTI 502 a, 502 b, 502 c, 502 d, and/or 502 e. A BTI can be created for each column of each table in the data. The BTI 502 a, 502 b, 502 c, 502 d, and/or 502 e can comprise a hash index. The BTI 502 a, 502 b, 502 c, 502 d, and/or 502 e can comprise first attributes and pointers to the table rows comprising the first attributes. For example, referring to the tables of FIG. 2 , an example BTI 502 a can comprise “Kalle=>0x29838” where Kalle is an attribute found in Table 2 and 0x29838 is a reference to the row in Table 2 where Kalle is stored in memory. Thus, the BTI 502 a, 502 b, 502 c, 502 d, and/or 502 e can be used to determine other attributes in other columns (e.g., second attributes, third attributes, etc. . . . ) in table rows comprising the first attributes. Accordingly, the BTI can be used to determine that an association exists between the first attributes and the other attributes.

The logical inference engine 106 can scan one or more of BTI 502 a, 502 b, 502 c, 502 d, and/or 502 e and create the BAI 503 a, 503 b, 503 c and/or 503 d. The BAI 503 a, 503 b, 503 c and/or 503 d can comprise a hash index. The BAI 503 a, 503 b, 503 c and/or 503 d can comprise an index configured for connecting attributes in a first table to common columns in a second table. The BAI 503 a, 503 b, 503 c and/or 503 d thus allows for identification of rows in the second table which then permits identification of other attributes in other tables. For example, referring to the tables of FIG. 2 , an example BAI 503 a can comprise “Kalle=>0x29838”, where Kalle is an attribute found in Table 2 and 0x39838 is a reference to a row in Table 4 that contains Kalle. In an aspect, the reference can be to a hash that can be in-memory or on disk.

Using the BTI 502 a, 502 b, 502 c, 502 d, and/or 502 e and the BAI 503 a, 503 b, 503 c, and/or 503 d, the logical inference engine 106 can generate an index window 504 by taking a portion of the data model 501 and mapping it into memory. The portion of the data model 501 taken into memory can be sequential (e.g., not random). The result is a significant reduction in the size of data required to be loaded into memory.

Thus, the logical inference engine 106 can determine a data subset based on user selections. The logical inference engine 106 automatically maintains associations among every piece of data in the entire data set used in an application. The logical inference engine 106 can store the binary state of every field and of every data table dependent on user selection (e.g., included or excluded). This can be referred to as a state space and can be updated by the logical inference engine 106 every time a selection is made. There is one bit in the state space for every value in the symbol table or row in the data table, as such the state space is smaller than the data itself and faster to query. The inference engine will work associating values or binary symbols into the dimension tuples. Dimension tuples are normally needed by a hypercube to produce a result.

The associations thus created by the logical inference engine 106 means that when a user makes a selection, the logical inference engine 106 can resolve (quickly) which values are still valid (e.g., possible values) and which values are excluded. The user can continue to make selections, clear selections, and make new selections, and the logical inference engine 106 will continue to present the correct results from the logical inference of those selections. In contrast to a traditional join model database, the associative model provides an interactive associative experience to the user.

FIG. 5C, illustrates an example application of one or more BTIs. User input 504 can be received that impacts a selection of one or more attribute states 506. Attribute states 506 can correspond to selection by a user of one or more attributes (e.g., values) found in Column 1 of Table X. In an aspect, the one or more attributes of Table X can comprise a hash of each respective attribute. One or more BTI's 508 can be accessed to determine one or more rows in Table X that comprise the attributes selected by the user. Row states 510 can correspond to selection of one or more rows found in Table X that comprise the one or more selected attributes. An inverted index 512 of Column 2 can be accessed to identify which rows of Table 1 comprise associated attributes. Attribute states 514 for Column 2 can be updated to reflect the associated attributes of Column 2. One or more BTI's 518 can be further accessed to determine other associated attributes in other columns as needed. Attribute states 514 can be applied to other tables via one or more BAIs. FIG. 5D illustrates an example of relationships identified by one or more BAIs.

FIG. 5E illustrates an example application of BTIs and BAIs to determine inter-table inferred states and intra-table inferred states using Table 1 and Table 2 of FIG. 2 . A BTI 520 can be generated for the “Client” attribute of Table 2. In an aspect, the BTI 520 can comprise an inverted index 521. In other aspect, the inverted index 521 can be considered a separate structure. The BTI 520 can comprise a row for each unique attribute in the “Client” column of Table 2. Each unique attribute can be assigned a corresponding position 522 in the BTI 520. In an aspect, the BTI 520 can comprise a hash for each unique attribute. The BTI 520 can comprise a column 523 for each row of Table 2. For each attribute, a “1” can indicate the presence of the attribute in the row and a “0” can indicate an absence of the attribute from the row. “0” and “1” are merely examples of values used to indicate presence or absence. Thus, the BTI 520 reflects that the attribute “Nisse” is found in rows 1 and 6 of Table 2, the attribute “Gullan” is found in row 2 of Table 2, the attribute “Kalle” is found in rows 3 and 4 of Table 2, and the attribute “Pekka” is found in row 5 of Table 2.

The inverted index 521 can be generated such that each position in the inverted index 521 corresponds to a row of Table 2 (e.g., first position corresponds to row 1, second position corresponds to row 2, etc. . . . ). A value can be entered into each position that reflects the corresponding position 522 for each attribute. Thus, in the inverted index 521, position 1 comprises the value “1” which is the corresponding position 522 value for the attribute “Nisse”, position 2 comprises the value “2” which is the corresponding position 522 value for the attribute “Gullan”, position 3 comprises the value “3” which is the corresponding position 522 value for the attribute “Kalle”, position 4 comprises the value “3” which is the corresponding position 522 value for the attribute “Kalle”, position 5 comprises the value “4” which is the corresponding position 522 value for the attribute “Pekka”, and position 6 comprises the value “1” which is the corresponding position 522 value for the attribute “Nisse”.

A BTI 524 can be generated for the “Product” attribute of Table 2. In an aspect, the BTI 524 can comprise an inverted index 525. In other aspect, the inverted index 525 can be considered a separate structure. The BTI 524 can comprise a row for each unique attribute in the “Product” column of Table 2. Each unique attribute can be assigned a corresponding position 526 in the BTI 524. In an aspect, the BTI 524 can comprise a hash for each unique attribute. The BTI 524 can comprise a column 527 for each row of Table 2. For each attribute, a “1” can indicate the presence of the attribute in the row and a “0” can indicate an absence of the attribute from the row. “0” and “1” are merely examples of values used to indicate presence or absence. Thus, the BTI 524 reflects that the attribute “Toothpaste” is found in row 1 of Table 2, the attribute “Soap” is found in rows 2, 3, and 5 of Table 2, and the attribute “Shampoo” is found in rows 4 and 6 of Table 2.

By way of example, the inverted index 525 can be generated such that each position in the inverted index 525 corresponds to a row of Table 2 (e.g., first position corresponds to row 1, second position corresponds to row 2, etc. . . . ). A value can be entered into each position that reflects the corresponding position 526 for each attribute. Thus, in the inverted index 525, position 1 comprises the value “1” which is the corresponding position 526 value for the attribute “Toothpaste”, position 2 comprises the value “2” which is the corresponding position 526 value for the attribute “Soap”, position 3 comprises the value “2” which is the corresponding position 526 value for the attribute “Soap”, position 4 comprises the value “3” which is the corresponding position 526 value for the attribute “Shampoo”, position 5 comprises the value “2” which is the corresponding position 526 value for the attribute “Soap”, and position 6 comprises the value “3” which is the corresponding position 526 value for the attribute “Shampoo”.

By way of example, a BTI 528 can be generated for the “Product” attribute of Table 1. In an aspect, the BTI 528 can comprise an inverted index 529. In other aspect, the inverted index 529 can be considered a separate structure. The BTI 528 can comprise a row for each unique attribute in the “Product” column of Table 1. Each unique attribute can be assigned a corresponding position 530 in the BTI 528. In an aspect, the BTI 528 can comprise a hash for each unique attribute. The BTI 528 can comprise a column 531 for each row of Table 1. For each attribute, a “1” can indicate the presence of the attribute in the row and a “0” can indicate an absence of the attribute from the row. “0” and “1” are merely examples of values used to indicate presence or absence. Thus, the BTI 528 reflects that the attribute “Soap” is found in row 1 of Table 1, the attribute “Soft Soap” is found in row 2 of Table 1, and the attribute “Toothpaste” is found in rows 3 and 4 of Table 1.

By way of example, the inverted index 529 can be generated such that each position in the inverted index 529 corresponds to a row of Table 1 (e.g., first position corresponds to row 1, second position corresponds to row 2, etc. . . . ). A value can be entered into each position that reflects the corresponding position 530 for each attribute. Thus, in the inverted index 529, position 1 comprises the value “1” which is the corresponding position 530 value for the attribute “Soap”, position 2 comprises the value “2” which is the corresponding position 530 value for the attribute “Soft Soap”, position 3 comprises the value “3” which is the corresponding position 530 value for the attribute “Toothpaste”, and position 4 comprises the value “3” which is the corresponding position 530 value for the attribute “Toothpaste”.

By way of example, a BAI 532 can be generated as an index between the product attribute of Table 2 and Table 1. The BAI 532 can comprise a row for each unique attribute in the BTI 524 by order of corresponding position 526. The value in each row can comprise the corresponding position 530 of the BTI 528. Thus, position 1 of the BAI 532 corresponds to “Toothpaste” in the BTI 524 (corresponding position 526 of 1) and comprises the value “3” which is the corresponding position 530 for “Toothpaste” of the BTI 528. Position 2 of the BAI 532 corresponds to “Soap” in the BTI 524 (corresponding position 526 of 2) and comprises the value “1” which is the corresponding position 530 for “Soap” of the BTI 528. Position 3 of the BAI 532 corresponds to “Shampoo” in the BTI 524 (corresponding position 526 of 3) and comprises the value “−1” which indicates that the attribute “Shampoo” is not found in Table 1.

By way of example, a BAI 533 can be created to create an index between the product attribute of Table 1 and Table 2. The BAI 533 can comprise a row for each unique attribute in the BTI 528 by order of corresponding position 530. The value in each row can comprise the corresponding position 526 of the BTI 524. Thus, position 1 of the BAI 533 corresponds to “Soap” in the BTI 528 (corresponding position 530 of 1) and comprises the value “2” which is the corresponding position 526 for “Soap” of the BTI 524. Position 2 of the BAI 533 corresponds to “Soft Soap” in the BTI 528 (corresponding position 530 of 2) and comprises the value “−1” which indicates that the attribute “Soft Soap” is not found in Table 2. Position 3 of the BAI 533 corresponds to “Toothpaste” in the BTI 528 (corresponding position 530 of 3) and comprises the value “1” which is the corresponding position 526 for “Toothpaste” of the BTI 524.

FIG. 5E illustrates an example application of the logical inference engine 106 utilizing the BTI 520, the BTI 524, and the BTI 528. A user can select the “Client” “Kalle” from within a user interface. A column for a user selection 534 of “Kalle” can be indicated in the BTI 520 comprising a value for each attribute that reflects the selection status of the attribute. Thus, the user selection 534 comprises a value of “0” for the attribute “Nisse” indicating that “Nisse” is not selected, the user selection 534 comprises a value of “0” for the attribute “Gullan” indicating that “Gullan” is not selected, the user selection 534 comprises a value of “1” for the attribute “Kalle” indicating that “Kalle” is selected, and the user selection 534 comprises a value of “0” for the attribute “Pekka” indicating that “Pekka” is not selected.

The BTI 520 can be consulted to determine that the attribute “Kalle” has a value of “1” in the column 523 corresponding to rows 3 and 4. In an aspect, the inverted index 521 can be consulted to determine that the user selection 534 relates to the position 522 value of “3” which is found in the inverted index 521 at positions 3 and 4, implicating rows 3 and 4 of Table 1. Following path 535, a row state 536 can be generated to reflect the user selection 534 as applied to the rows of Table 2. The row state 536 can comprise a position that corresponds to each row and a value in each position reflecting whether a row was selected. Thus, position 1 of the row state 536 comprises the value “0” indicating that row 1 does not contain “Kalle”, position 2 of the row state 536 comprises the value “0” indicating that row 2 does not contain “Kalle”, position 3 of the row state 536 comprises the value “1” indicating that row 3 does contain “Kalle”, position 4 of the row state 536 comprises the value “1” indicating that row 4 does contain “Kalle”, position 5 of the row state 536 comprises the value “0” indicating that row 5 does not contain “Kalle”, and position 6 of the row state 536 comprises the value “0” indicating that row 6 does not contain “Kalle”.

Following path 537, the row state 536 can be compared with the inverted index 525 to determine the corresponding position 526 contained in the inverted index 525 at positions 3 and 4. The inverted index 525 comprises the corresponding position 526 value of “2” in position 3 and the corresponding position 526 value of “3” in position 4. Following path 538, the corresponding position 526 values of “2” and “3” can be determined to correspond to “Soap” and “Shampoo” respectively in the BTI 524. Thus, the logical inference engine 106 can determine that both “Soap” and “Shampoo” in Table 2 are associated with “Kalle” in Table 2. The association can be reflected in an inferred state 539 in the BTI 524. The inferred state 539 can comprise a column with a row for each attribute in the BTI 524. The column can comprise a value indicated the selection state for each attribute. The inferred state 539 comprises a “0” for “Toothpaste” indicating that “Toothpaste” is not associated with “Kalle”, the inferred state 539 comprises a “1” for “Soap” indicating that “Soap” is associated with “Kalle”, and inferred state 539 comprises a “1” for “Shampoo” indicating that “Shampoo” is associated with “Kalle”.

Following path 540, the inferred state 539 can be compared to the BAI 532 to determine one or more associations between the selection of “Kalle” in Table 2 and one or more attributes in Table 1. As the inferred state 539 comprises a value of “1” in both position 2 and position 3, the BAI 532 can be assessed to determine the values contained in position 2 and position 3 of the BAI 532 (following path 541). Position 2 of the BAI 532 comprises the value “1” which identifies the corresponding position 530 of “Soap” and position 3 of the BAI 532 comprises the value “−1” which indicates that Table 1 does not contain “Shampoo”. Thus, the logical inference engine 106 can determine that “Soap” in Table 1 is associated with “Kalle” in Table 2. The association can be reflected in an inferred state 542 in the BTI 528. The inferred state 542 can comprise a column with a row for each attribute in the BTI 528. The column can comprise a value indicated the selection state for each attribute. The inferred state 542 comprises a “1” for “Soap” indicating that “Soap” is associated with “Kalle”, the inferred state 542 comprises a “0” for “Soft Soap” indicating that “Soft Soap” is not associated with “Kalle”, and the inferred state 542 comprises a “0” for “Toothpaste” indicating that “Toothpaste” is not associated with “Kalle”. Based on the current state of BTIs and BAIs, if the data sources 102 indicate that an update or delta change has occurred to the underlying data, the BTIs and BAIs can be updated with corresponding changes to maintain consistency.

Based on current selections and possible rows in data tables a calculation/chart engine 108 can calculate aggregations in objects forming transient hyper cubes in an application. The calculation/chart engine 108 can further build a virtual temporary table from which aggregations can be made. The calculation/chart engine 108 can perform a calculation (e.g., evaluate an expression in response to a user selection/de-selection) via a multithreaded operation. The state space can be queried to gather all of the combinations of dimensions and values necessary to perform the calculation. In an aspect, the query can be on one thread per object, one process, one worker, combinations thereof, and the like. The expression can be calculated on multiple threads per object. Results of the calculation can be passed to a rendering engine 116 and/or optionally to an extension engine 110.

Optionally, the extension engine 110 can be implemented to communicate data via an interface 112 to an external engine 114. In another aspect, the extension engine 110 can communicate data, metadata, a script, a reference to one or more artificial neural networks (ANNs), one or more commands to be executed, one or more expressions to be evaluated, combinations thereof, and the like to the external engine 114. The interface 114 can comprise, for example, an Application Programming Interface (API). The external engine 114 can comprise one or more data processing applications (e.g., simulation applications, statistical applications, mathematical computation applications, database applications, combinations thereof, and the like). The external engine 114 can be, for example, one or more of MATLAB®, R, Maple®, Mathematica®, combinations thereof, and the like.

In an aspect, the external engine 114 can be local to the associative data indexing engine 100 or the external engine 114 can be remote from the associative data indexing engine 100. The external engine 114 can perform additional calculations and transmit the results to the extension engine 110 via the interface 112. A user can make a selection in the data model of data to be sent to the external engine 114. The logical inference engine 106 and/or the extension engine 110 can generate data to be output to the external engine 114 in a format to which the external engine 114 is accustomed to processing. In an example application, tuples forming a hypercube can comprise two dimensions and one expression, such as (Month, Year, Count (ID)), ID being a record identification of one entry. Then said tuples can be exchanged with the external engine 114 through the interface 112 as a table. If the data comprise births there can be timestamps of the births and these can be stored as month and year. If a selection in the data model will give a set of month-year values that are to be sent out to an external unit, the logical inference engine 106 and/or the extension engine 110 can ripple that change to the data model associatively and produce the data (e.g., set and/or values) that the external engine 114 needs to work with. The set and/or values can be exchanged through the interface 112 with the external engine 114. The external engine 114 can comprise any method and/or system for performing an operation on the set and/or values. In an aspect, operations on the set and/or values by the external engine 114 can be based on tuples (aggregated or not). In an aspect, operations on the set and/or values by the external engine 114 can comprise a database query based on the tuples. Operations on the set and/or values by the external engine 114 can be any transformation/operation of the data as long as the cardinality of the result is consonant to the sent tuples/hypercube result.

In an aspect, tuples that are transmitted to the external engine 114 through the interface 112 can result in different data being received from the external engine 114 through the interface 112. For example, a tuple consisting of (Month, Year, Count (ID)) should return as 1-to-1, m-to-1 (where aggregations are computed externally) or n-to-n values. If data received are not what were expected, association can be lost. Transformation of data by the external engine 114 can be configured such that cardinality of the results is consonant to the sent tuples and/or hypercube results. The amount of values returned can thus preserve associativity.

Results received by the extension engine 110 from the external engine 114 can be appended to the data model. In an aspect, the data can be appended to the data model without intervention of the script engine 104. Data model enrichment is thus possible “on the fly.” A natural work flow is available allowing clicking users to associatively extend the data. The methods and systems disclosed permit incorporation of user implemented functionality into a presently used work flow. Interaction with third party complex computation engines, such as MATLAB® or R, is thus facilitated.

The logical inference engine 106 can couple associated results to the external engine 114 within the context of an already processed data model. The context can comprise tuple or tuples defined by dimensions and expressions computed by hypercube routines. Association is used for determination of which elements of the present data model are relevant for the computation at hand. Feedback from the external engine 114 can be used for further inference inside the inference engine or to provide feedback to the user.

A rendering engine 116 can produce a desired graphical object (charts, tables, etc) based on selections/calculations. When a selection is made on a rendered object there can be a repetition of the process of moving through one or more of the logical inference engine 106, the calculation/chart engine 108, the extension engine 110, the external engine 114, and/or the rendering engine 116. The user can explore the scope by making different selections, by clicking on graphical objects to select variables, which causes the graphical object to change. At every time instant during the exploration, there exists a current state space, which is associated with a current selection state that is operated on the scope (which always remains the same).

Different export features or tools 118 can be used to publish, export or deploy any output of the associative data indexing engine 100. Such output can be any form of visual representation, including, but not limited to, textual, graphical, animation, audio, tactile, and the like.

An example database, as shown in FIG. 2 , can comprise a number of data tables (Tables 1-5). Each data table can contain data values of a number of data variables. For example, in Table 1 each data record contains data values of the data variables “Product,” “Price,” and “Part.” If there is no specific value in a field of the data record, this field is considered to hold a NULL-value. Similarly, in Table 2 each data record contains values of the variables “Date,” “Client,” “Product,” and “Number.” In Table 3 each data record contains values of variable “Date” as “Year,” “Month” and “Day.” In Table 4 each data record contains values of variables “Client” and “Country,” and in Table 5 each data record contains values of variables “Country,” “Capital,” and “Population.” Typically, the data values are stored in the form of ASCII-coded strings, but can be stored in any form.

The methods provided can be implemented by means of a computer program as illustrated in a flowchart of a method 300 in FIG. 3 . In a step 302, the program can read some or all data records in the database, for instance using a SELECT statement which selects all the tables of the database, e.g. Tables 1-5. In an aspect, the database can be read into primary memory of a computer.

To increase evaluation speed, each unique value of each data variable in said database can be assigned a different binary code and the data records can be stored in binary-coded form. This can be performed, for example, when the program first reads the data records from the database. For each input table, the following steps can be carried out. The column names, e.g. the variables, of the table can be read (e.g., successively). Every time a new data variable appears, a data structure can be instantiated for the new data variable. An internal table structure can be instantiated to contain some or all the data records in binary form, whereupon the data records can be read (e.g., successively) and binary-coded. For each data value, the data structure of the corresponding data variable can be checked to establish if the value has previously been assigned a binary code. If so, that binary code can be inserted in the proper place in the above-mentioned table structure. If not, the data value can be added to the data structure and assigned a new binary code, for example the next binary code in ascending order, before being inserted in the table structure. In other words, for each data variable, a unique binary code can be assigned to each unique data value.

After having read some or all data records in the database, the program can analyze the database in a step 304 to identify all connections between the data tables. A connection between two data tables means that these data tables have one variable in common. In an aspect, step 304 can comprise generation of one or more bidirectional table indexes and one or more bidirectional associative indexes. In an aspect, generation of one or more bidirectional table indexes and one or more bidirectional associative indexes can comprise a separate step. In another aspect, generation of one or more bidirectional table indexes and one or more bidirectional associative indexes can be on demand. After the analysis, all data tables are virtually connected. In FIG. 2 , such virtual connections are illustrated by double ended arrows. The virtually connected data tables can form at least one so-called “snowflake structure,” a branching data structure in which there is one and only one connecting path between any two data tables in the database. Thus, a snowflake structure does not contain any loops. If loops do occur among the virtually connected data tables, e.g. if two tables have more than one variable in common, a snowflake structure can in some cases still be formed by means of special algorithms known in the art for resolving such loops.

After this initial analysis, the user can explore the database. In doing so, the user defines in a step 306 a mathematical function, which could be a combination of mathematical expressions. Assume that the user wants to extract the total sales per year and client from the database in FIG. 2 . The user defines a corresponding mathematical function “SUM (x*y)”, and selects the calculation variables to be included in this function: “Price” and “Number.” The user also selects the classification variables: “Client” and “Year.”

The computer program then identifies in a step 308 all relevant data tables, e.g. all data tables containing any one of the selected calculation and classification variables, such data tables being denoted boundary tables, as well as intermediate data tables in the connecting path(s) between these boundary tables in the snowflake structure, such data tables being denoted connecting tables. There are no connecting tables in the present example. In an aspect, one or more bidirectional table indexes and one or more bidirectional associative indexes can be accessed as part of step 308.

In the present example, all occurrences of every value, e.g. frequency data, of the selected calculation variables can be included for evaluation of the mathematical function. In FIG. 2 , the selected variables (“Price,” “Number”) can require such frequency data. Now, a subset (B) can be defined that includes all boundary tables (Tables 1-2) containing such calculation variables and any connecting tables between such boundary tables in the snowflake structure. It should be noted that the frequency requirement of a particular variable is determined by the mathematical expression in which it is included. Determination of an average or a median calls for frequency information. In general, the same is true for determination of a sum, whereas determination of a maximum or a minimum does not require frequency data of the calculation variables. It can also be noted that classification variables in general do not require frequency data.

Then, a starting table can be selected in a step 310, for example, among the data tables within subset (B). In an aspect, the starting table can be the data table with the largest number of data records in this subset. In FIG. 2 , Table 2 can be selected as the starting table. Thus, the starting table contains selected variables (“Client,” “Number”), and connecting variables (“Date,” “Product”). These connecting variables link the starting table (Table 2) to the boundary tables (Tables 1 and 3).

Thereafter, a conversion structure can be built in a step 312. This conversion structure can be used for translating each value of each connecting variable (“Date,” “Product”) in the starting table (Table 2) into a value of a corresponding selected variable (“Year,” “Price”) in the boundary tables (Table 3 and 1, respectively). A table of the conversion structure can be built by successively reading data records of Table 3 and creating a link between each unique value of the connecting variable (“Date”) and a corresponding value of the selected variable (“Year”). It can be noted that there is no link from value 4 (“Date: 1999-01-12”), since this value is not included in the boundary table. Similarly, a further table of the conversion structure can be built by successively reading data records of Table 1 and creating a link between each unique value of the connecting variable (“Product”) and a corresponding value of the selected variable (“Price”). In this example, value 2 (“Product: Toothpaste”) is linked to two values of the selected variable (“Price: 6.5”), since this connection occurs twice in the boundary table. Thus, frequency data can be included in the conversion structure. Also note that there is no link from value 3 (“Product: Shampoo”).

When the conversion structure has been built, a virtual data record can be created. Such a virtual data record accommodates all selected variables (“Client,” “Year,” “Price,” “Number”) in the database. In building the virtual data record, a data record is read in a step 314 from the starting table (Table 2). Then, the value of each selected variable (“Client”, “Number”) in the current data record of the starting table can be incorporated in the virtual data record in a step 316. Also, by using the conversion structure each value of each connecting variable (“Date”, “Product”) in the current data record of the starting table can be converted into a value of a corresponding selected variable (“Year”, “Price”), this value also being incorporated in the virtual data record.

In a step 318 the virtual data record can be used to build an intermediate data structure. Each data record of the intermediate data structure can accommodate each selected classification variable (dimension) and an aggregation field for each mathematical expression implied by the mathematical function. The intermediate data structure can be built based on the values of the selected variables in the virtual data record. Thus, each mathematical expression can be evaluated based on one or more values of one or more relevant calculation variables in the virtual data record, and the result can be aggregated in the appropriate aggregation field based on the combination of current values of the classification variables (“Client,” “Year”).

The above procedure can be repeated for one or more additional (e.g., all) data records of the starting table. In a step 320 it can be checked whether the end of the starting table has been reached. If not, the process can be repeated from step 314 and further data records can be read from the starting table. Thus, an intermediate data structure can be built by successively reading data records of the starting table, by incorporating the current values of the selected variables in a virtual data record, and by evaluating each mathematical expression based on the content of the virtual data record. If the current combination of values of classification variables in the virtual data record is new, a new data record can be created in the intermediate data structure to hold the result of the evaluation. Otherwise, the appropriate data record is rapidly found, and the result of the evaluation is aggregated in the aggregation field.

Thus, data records can be added to the intermediate data structure as the starting table is traversed. The intermediate data structure can be a data table associated with an efficient index system, such as an AVL or a hash structure. The aggregation field can be implemented as a summation register, in which the result of the evaluated mathematical expression is accumulated.

In some aspects, e.g. when evaluating a median, the aggregation field can be implemented to hold all individual results for a unique combination of values of the specified classification variables. It should be noted that only one virtual data record is needed in the procedure of building the intermediate data structure from the starting table. Thus, the content of the virtual data record can be updated for each data record of the starting table. This can minimize the memory requirement in executing the computer program.

After traversing the starting table, the intermediate data structure can contain a plurality of data records. If the intermediate data structure accommodates more than two classification variables, the intermediate data structure can, for each eliminated classification variable, contain the evaluated results aggregated over all values of this classification variable for each unique combination of values of remaining classification variables.

When the intermediate data structure has been built, a final data structure, e.g., a multidimensional cube, as shown in non-binary notation in Table 6 of FIG. 4 , can be created in a step 322 by evaluating the mathematical function (“SUM (x*y)”) based on the results of the mathematical expression (“x*y”) contained in the intermediate data structure. In doing so, the results in the aggregation fields for each unique combination of values of the classification variables can be combined. In the example, the creation of the final data structure is straightforward, due to the trivial nature of the present mathematical function. The content of the final data structure can be presented to the user, for example in a two-dimensional table, in a step 324, as shown in Table 7 of FIG. 4 . Alternatively, if the final data structure contains many dimensions, the data can be presented in a pivot table, in which the user can interactively move up and down in dimensions, as is well known in the art. At step 326, input from the user can be received. For example, input from the user can be a selection and/or de-selection of the presented results.

Optionally, input from the user at step 326 can comprise a request for external processing. In an aspect, the user can be presented with an option to select one or more external engines to use for the external processing. Optionally, at step 328, data underlying the user selection can be configured (e.g., formatted) for use by an external engine. Optionally, at step 330, the data can be transmitted to the external engine for processing and the processed data can be received. The received data can undergo one or more checks to confirm that the received data is in a form that can be appended to the data model. For example, one or more of an integrity check, a format check, a cardinality check, combinations thereof, and the like. Optionally, at step 332, processed data can be received from the external engine and can be appended to the data model as described herein. In an aspect, the received data can have a lifespan that controls how long the received data persists with the data model. For example, the received data can be incorporated into the data model in a manner that enables a user to retrieve the received data at another time/session. In another example, the received data can persist only for the current session, making the received data unavailable in a future session.

FIG. 5A illustrates how a selection 50 operates on a scope 52 of presented data to generate a data subset 54. The data subset 54 can form a state space, which is based on a selection state given by the selection 50. In an aspect, the selection state (or “user state”) can be defined by a user clicking on list boxes and graphs in a user interface of an application. An application can be designed to host a number of graphical objects (charts, tables, etc.) that evaluate one or more mathematical functions (also referred to as an “expression”) on the data subset 54 for one or more dimensions (classification variables). The result of this evaluation creates a chart result 56 which can be a multidimensional cube which can be visualized in one or more of the graphical objects.

The application can permit a user to explore the scope 52 by making different selections, by clicking on graphical objects to select variables, which causes the chart result 56 to change. At every time instant during the exploration, there exists a current state space, which can be associated with a current selection state that is operated on the scope 52 (which always remains the same).

As illustrated in FIG. 5A, when a user makes a selection, the inference engine 18 calculates a data subset. Also, an identifier ID1 for the selection together with the scope can be generated based on the filters in the selection and the scope. Subsequently, an identifier ID2 for the data subset is generated based on the data subset definition, for example a bit sequence that defines the content of the data subset. ID2 can be put into a cache using ID1 as a lookup identifier. Likewise, the data subset definition can be put in the cache using ID2 as a lookup identifier.

As shown in FIG. 5A, a chart calculation in a calculation/chart engine 58 takes place in a similar way. Here, there are two information sets: the data subset 54 and relevant chart properties 60. The latter can be, but not restricted to, a mathematical function together with calculation variables and classification variables (dimensions). Both of these information sets can be used to calculate the chart result 56, and both of these information sets can be also used to generate identifier ID3 for the input to the chart calculation. ID2 can be generated already in the previous step, and ID3 can be generated as the first step in the chart calculation procedure.

The identifier ID3 can be formed from ID2 and the relevant chart properties. ID3 can be seen as an identifier for a specific chart generation instance, which can include all information needed to calculate a specific chart result. In addition, a chart result identifier ID4 can be created from the chart result definition, for example a bit sequence that defines the chart result 56. ID4 can be put in the cache using ID3 as a lookup identifier. Likewise, the chart result definition can be put in the cache using ID4 as a lookup identifier.

Optionally, further calculations, transforming, and/or processing can be included through an extension engine 62. Optionally, associated results from the inference engine 18 and further computed by hypercube computation in said calculation/chart engine 58 can be coupled to an external engine 64 that can comprise one or more data processing applications (e.g., simulation applications, statistical applications, mathematical computation applications, database applications, combinations thereof, and the like). Context of a data model processed by the inference engine 18 can comprise a tuple or tuples of values defined by dimensions and expressions computed by hypercube routines. Data can be exchanged through an interface 66.

The associated results coupled to the external engine 64 can be intermediate. Further results that can be final hypercube results can also be received from the external engine 64. Further results can be fed back to be included in the Data/Scope 52 and enrich the data model. The further results can also be rendered directly to the user in the chart result 56. Data received from and computed by the external engine 64 can be used for further associative discovery.

Each of the data elements of the database shown in Tables 1-5 of FIG. 2 has a data element type and a data element value (for example “Client” is the data element type and “Nisse” is the data element value). Multiple records can be stored in different database structures such as data cubes, data arrays, data strings, flat files, lists, vectors, and the like; and the number of database structures can be greater than or equal to one and can comprise multiple types and combinations of database structures. While these and other database structures can be used with, and as part of, the methods and systems disclosed, the remaining description will refer to tables, vectors, strings and data cubes solely for convenience.

Additional database structures can be included within the database illustrated as an example herein, with such structures including additional information pertinent to the database such as, in the case of products for example; color, optional packages, etc. Each table can comprise a header row which can identify the various data element types, often referred to as the dimensions or the fields, that are included within the table. Each table can also have one or more additional rows which comprise the various records making up the table. Each of the rows can contain data element values (including null) for the various data element types comprising the record.

The database as referred to in Tables 1-5 of FIG. 2 can be queried by specifying the data element types and data element values of interest and by further specifying any functions to apply to the data contained within the specified data element types of the database. The functions which can be used within a query can include, for example, expressions using statistics, sub-queries, filters, mathematical formulas, and the like, to help the user to locate and/or calculate the specific information wanted from the database. Once located and/or calculated, the results of a query can be displayed to the user with various visualization techniques and objects such as list boxes of a user interface illustrated in FIG. 6 .

The graphical objects (or visual representations) can be substantially any display or output type including graphs, charts, trees, multi-dimensional depictions, images (computer generated or digital captures), video/audio displays describing the data, hybrid presentations where output is segmented into multiple display areas having different data analysis in each area and so forth. A user can select one or more default visual representations; however, a subsequent visual representation can be generated on the basis of further analysis and subsequent dynamic selection of the most suitable form for the data.

In an aspect, a user can select a data point and a visualization component can instantaneously filter and re-aggregate other fields and corresponding visual representations based on the user's selection. In an aspect, the filtering and re-aggregation can be completed without querying a database. In an aspect, a visual representation can be presented to a user with color schemes applied meaningfully. For example, a user selection can be highlighted in green, datasets related to the selection can be highlighted in white, and unrelated data can be highlighted in gray. A meaningful application of a color scheme provides an intuitive navigation interface in the state space.

The result of a standard query can be a smaller subset of the data within the database, or a result set, which is comprised of the records, and more specifically, the data element types and data element values within those records, along with any calculated functions, that match the specified query. For example, as indicated in FIG. 6 , the data element value “Nisse” can be specified as a query or filtering criteria as indicated by a frame in the “Client” header row. In some aspects, the selected element can be highlighted in green. By specifically selecting “Nisse,” other data element values in this row are excluded as shown by gray areas. Further, “Year” “1999” and “Month” “January” are selected in a similar way.

Optionally, in this application, external processing can also be requested by ticking “External” in the user interface of FIG. 6 . Data as shown in FIG. 7 can be exchanged with an External engine 64 through the interface 66 of FIG. 5A. In addition to evaluating the mathematical function (“SUM (Price*Number)”) based on the results of the mathematical expression (“Price*Number”) contained in the intermediate data structure the mathematical function (“SUM (ExtFunc(Price*Number))”) can be evaluated. Data sent out are (Nisse, 1999, January, {19.5, null}). In this case the external engine 64 can process data in accordance with the formula

if (x==null)  y=0.5 else  y=x as shown in in FIG. 7 . The result input through the interface 66 will be (19.5, 0.5) as reflected in the graphical presentation in FIG. 6 .

In a further aspect, external processing can also be optionally requested by ticking “External” in a box as shown in FIG. 8 . Data as shown in FIG. 9 can be exchanged with an external engine 64 through the Interface 66 of FIG. 5A. In addition to evaluating the mathematical function (“SUM(Price*Number)”) based on the results of the mathematical expression (“Price*Number”) contained in the intermediate data structure the mathematical function

SUM(ExtFunc(Price*Number))

can be evaluated. Data sent out are (Nisse, 1999, January, {19.5, null}). In this case the external engine 64 will process data in accordance with Function (1) as shown below and in FIG. 9 . The result input through the Interface 66 will be (61.5) as reflected in the graphical presentation in FIG. 8 .

Function (1) y=ExtAggr(x[ ])  for (x in x[ ])   if (x==null)    y=y + 42   else    y=y+x

A further optional embodiment is shown in FIG. 10 and FIG. 11 . The same basic data as in previous examples apply. A user selects “Pekka,” “1999,” “January,” and “External.” By selecting “External,” already determined and associated results are coupled to the external engine 64. Feedback data from the external engine 64 based on an external computation, ExtQualification(Sum(Price*Number)), as shown in FIG. 13 will be the information “MVG.” This information can be fed back to the logical inference engine 18. The information can also be fed back to the graphical objects of FIG. 10 and as a result a qualification table 68 will highlight “MVG” (illustrated with a frame in FIG. 10 ). Other values (U, G, and VG) are shown in gray areas. The result input through the Interface 66 will be Soap with a value of 75 as reflected in the graphical presentation (bar chart) of FIG. 10 . FIG. 11 is a schematic representation of data exchanged with an external engine based on selections in FIG. 10 . FIG. 12 is a table showing results from computations based on different selections in the presentation of FIG. 10 .

Should a user instead select “Gullan,” “1999,” “January,” and “External,” the feedback signal would include “VG” based on the content shown in qualification table 68. The computations actually performed in the external engine 62 are not shown or indicated, since they are not relevant to the inference engine.

In FIG. 13 a user has selected “G” as depicted by 70 in the qualification table 68. As a result information fed back from the external engine 64 to the external engine 62 and further to the inference engine 18 the following information will be highlighted: “Nisse,” “1999,” and “January” as shown in FIG. 13 . Furthermore, the result produced will be Soap 37.5 as reflected in the graphical presentation (bar chart) of FIG. 13 .

 16. The one or more non-transitory computer-readable media of claim 15, wherein each of the one or more vectors of similarities is associated with a field, of the one or more fields, and comprises a similarity score based on that field.
 17. The one or more non-transitory computer-readable media of claim 15, wherein the processor-executable instructions that cause the at least one computing device to determine the one or more vectors of similarities further cause the at least one computing device to: determine, for each pair of records of the plurality of records and for each field of the one or more fields, the one or more vectors of similarities.
 18. The one or more non-transitory computer-readable media of claim 15, wherein each field of the plurality of fields comprises a field type of a plurality of field types, and wherein the plurality of field types comprises one or more of numeric, categorical, date, time, or geolocation.
 19. The one or more non-transitory computer-readable media of claim 15, wherein the one or more graphical objects are associated with a subset of records of the plurality of records, and wherein the subset of records is associated with the one or more fields indicated by the selection.
 20. The one or more non-transitory computer-readable media of claim 19, wherein the processor-executable instructions further cause the at least one computing device to generate, based on the subset of records, a data model.
